PLASTER-SOWER.

TO ALL WHOM IT MAY CONCERJ:

Be it known that I, F. P. CULLOM, of Dowagiac, Cass county, State of Michigan, have invented a new and improved Plaster-Sewer; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which-f Figure 1 is a longitudinal section taken in the vertical plane y y, indicated in tig. 2. I

Figure 2 is a section taken in thel horizontal plane a* ne, indicated in iig. 1.

Similar letters of reference `indicate corresponding parts in the two figures.

This invention relates to a new and useful improvement on machines for scattering plaster.

It consists inconstructing the hopper, from which the plaster is discharged, with two movable inclined sides, having their inner surfaces serrated or corrugated, one of which sides receives a reciprocating motion for pulverizing and distributing the plaster, and the other'is adjustable for regulating the amount of discharge from the hopper, as will be hereinafter described.

To enable others skilled in the art'to understand my invention, I will describe its construction and operation.

In the accompanying` drawings A represents the axle-tree of tivo t1ansporting-wl1eels B B', and Cil-epresents a frame, which is secured to and extended forward of said axle-tree, and designed for supporting the hopper. This hopper consists of two vertical end pieces a a, which are secured rigidly to the longitudinal beams of frame C, two inclined side plates In', a rectilinear reciprocating slide, c, and a cover, d. The rear side plate is secured rigidly at its ends to the end'pieccs a a, and the front sido plate Zi is pivoted to said end pieces, so that its lower edge can be adjusted toward or from the lower edg'eof the slide c, for increasing or diminishing thc opening through which the plaster is discharged. For the purpose of adjusting this front plate with facility, and securing it in any desired position, two rods, c e, are attached to its lower edge, and passed forward through holes which are made through one ot' the transverse bars of frame C, The set-screwsfj', which are tapped int said bar just over the rods c c, arc used for binding and holding these rods, and of course the pivoted plate b. The reciprocating slide c is fitted into the inner and lower side of the rear plate as shown in iig. l, so as to be moved freely; and this slide extends through both end pieces of the hopper through openings made for it. From the rear side of' the slide e short lugs project, andpass freely through oblong slots, which are made through the stationary plate l. vTe the' outer` ends of these lugs, outside oi' the hopper, a bnr, g is secured, to whicha Pitman-red, g, is suitably pivotcd, as shown in g. 2. This Pitman-rod is connected to a crank of the longitudinal crankshaft L, which has its bearings invbrackets igt', projecting from the frame C. A bevel spur-Wheel, d'1 on 'the cranl -shaft 7L, engages with the teeth of a bevel-face wheel, K, on the driving -and transporting-wheel B', so that when the machine is moved along, this wheel will communicate rapid reciprocatingm'otion to the slide e in the hopper. The slide c has its inner face grooved or corrugated vertically, and a corresponding portion of the inner surface of the plate I1 is also grooved or corrugated in a similar manner, us shown in figs. 2 and 3.

The effect of Vthe corrugated surfaces and the reciprocating slide c is to pulvcrize the plaster as it descends toward the discharge aperture. The vertical channels and ribs of the corrugated surfaces will prevent the plaster from clogging, and cause a froc and uninterrupted flow of the plaster through the space formed between the lower edges of the plate b and slide c. The driver is located in rear of the hopper upon a seat, E, which is supported by thc axle-tree A, and the horse for drawing the machine along is hitched to the thills F, which are secured to the frame C in front of the hopper.

Having described my invention, what I claim as new, and desire to secure by Letters Patentl` l. The construction of the hopper of a plastersewer, of stationary ends ct n, stationary inclined side b, reciprocating slide c, and pivoted adjustable side plate t', substantially as described.`

2. The corrugating of the inner surface of the slide c, in combination with the corrugated side plate and means for regulating the discharge oi plaster from the hopper, substantially as described and for the purposes set forth.
